I IMPROVEMENT IN UMRELaA-RUNNERS The Schedule .referred to in these LettrsjPatentand making part of the same.

To all 'it' 'may concern Be it known that I, 'HORACE'.L. ROBBINS, of Boston, county Vof Suffolk,` and State" of Massachusetts, have invented a new andnseful Improvement in Run- 4ners for Umbrellas'and'larasols; and I do hereby declare 'that the following is a full, clear, and exact desciiption of the construction and operation of the same, reference being had to the `annexed drawings,

making a part ot' this specification, in whieh-l Figure' 1 is a side view of a runner having my improvement applied to it.

'Figure 2 is a longitudinal section of the same.

Figures 3 and 4 are views of the innersliding tube detachedv from the runner.

Figure is a view of a runner, with the inner sliding tube partially withdrawn. l

Figure 6 is a longitudinal Sectionof arunner and umbrella-handle, showing the position of the runner when the umbrella is closed. Y l

Similar letters refer to like parts in the diii'erent drawings.

a is the runner. i f,

b is a chamber on the side of the runner.

c'is a sliding tube inside the runnen d is a stop-device on the tube c.Y

e is'a slot in the tube c.

f is the umbrella-handle.

Vg is the fastening-spring ofthe umbrella.

h is a key-hole.

The nature of my invention vconsists in providing runners for umbrellas and parasols with a looking-device Without the inconvenience ofV a` key.

I construct my runner with a` chamber, b, on the side of it.

Y When the umbrella is closed, the fastening-spring of the umbrella-handle passes into this chamber, and the umbrella is locked.

I nside the runner, I arrange the tube c, having a slot coincident with that communicating with the ellamber in the runner.

` When vI wish to open the umbrella, I partially withdraw the tube c, as seen in fig. 5, which operation depresses the fasten'ingfspring g, thereby releasing .the

runner or unlocking the umbrella. v

The projecting lips dserve asa'stop-device to prevent the tube frornbeing withdrawn too far.

`By making the sides of" the slot e in `the tube c in the form of a cam, the umbrella may be unlocked by revolving the tube, instead oi" withdrawing it.

To render the umbrella still more secure from being dishonestly appropriated, I 4make a key-hole, h, in the chamber b, which is of no use, except to mislead those unacquainted with the operation of the inner sliding tube. v

1. An umbrella-runner, provided with an inner sliding or revolving unlocking-tube, substantiallyasI described.

2. The combination of the runner a and sliding tube c, substantially as described and for the purpose specied.

3. The chamber b, in combination with the runner a and sliding tube c, substantially as described, and

for the purpose specilied.
